World War II: Following the American capture of Makin Atoll, USS Liscome Bay was sunk by a torpedo from Japanese submarine I-175, killing 644.

World War II or the Second World War was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II is the deadliest conflict in history, causing the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

The Battle of Makin was an engagement of the Pacific campaign of World War II, fought from 20 to 24 November 1943 on Makin Atoll in the Gilbert Islands.

USS Liscome Bay (ACV/CVE-56) was the second of fifty Casablanca-class escort carriers built to serve the United States Navy during World War II. Launched in April 1943 and commissioned the following August, she was named for Liscome Bay in Dall Island in the Alexander Archipelago of Alaska. On 24 November 1943, her munitions were catastrophically detonated by a torpedo attack by the Japanese submarine I-175 while she was acting as the flagship of Carrier Division 24, which was supporting operations on Makin. She quickly sank with the loss of 702 officers and sailors. Her loss is the deadliest sinking of a carrier in the history of the United States Navy.

A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially, a fish. The term torpedo originally applied to a variety of devices, most of which would today be called mines. From about 1900, torpedo has been used strictly to designate a self-propelled underwater explosive device.
